Answer

In type Ib pseudohypoparathyroidism, patients do not present with the somatic features of AHO. These patients have normal Gs-alpha protein, with hormonal resistance to PTH—an impaired cAMP response to PTH, suggesting that the defect lies on the receptor. At what level the receptor is affected is not yet clear.
